Photonics is a strongly growing sector of the economy and a major research area in Europe. In Thuringia and in particular in Jena, the scientific and industrial location is shaped by universities, research institutes and companies in the field of optics and photonics. While the number of young, well-trained female graduates is high, women who hold a leading position in academia and high-tech industry are still underrepresented.
The scientific profile of the research group Biopolarisation aims at the application and further development of a novel technological approach, which utilises the interaction of the electromagnetic near-field of optically polarised biological species with a conducting tip of an atomic force microscope for characterising the biological species. The signal evaluation using Kelvin Probe Force Microscopy is independent of noisy scattering light which otherwise contributes to the signal in the frequently used optical evaluation methods. Thus, it provides accuracies enhanced by several orders of magnitude. The new scientific approach complements investigation methods for the characterisation of biological species that are already established at the Leibniz-IPHT. In particular, it will be exploited in collaboration with the Jenaer Biochip Initiative.
A further scientific topic is the characterisation and improvement of chips with implanted pattern of near surface charges. Preliminary investigation of such PolCarrTM-Chips demonstrated stable adsorption of DEAE-DEXTRAN(+) at the implanted region. This opens up a large variety of promising possibilities for specific adsorption of biological species. In particular, it allows for characterisation of biological matter directly adsorbed from solution without the necessity of drying the sample.
Gained interest? Our group is developing and we are looking forward to further collaborations. In particular, we welcome students for Bachelor and Master projects.
